To all 4uv/zerrz- 'it may mnrfru:

Be it l-:nown that: l, JAMES Tiroxms lim- BURN, of ri'iehend. lmzhwinnnvh, l'hnfre..' shire, Scotland, have invented Cerwin new und useful lmpi'ox-'enlents in hiordfairs, of -which the lellmviug is a spemlif'zitfinn.

This invention relates m motor mrs ol' thinlrlns: wherein lze hedy sr roar-h work rests on a frame which i; so construct-ed :is Lo h(- wilxonb unduly straining the frame or injuring' the mechanism, mol-ion being c-.onwyed from the through v. dliving sha-.fr and worn; or bevel gaming.

i'runnions without putting the gear out of alinenu-nri.

wheeled mar made in :wcord'uni'e with my invention. Fig. is v.- plzin ol theV saine with the body removed. lf'ig'. I) is n. side elevubnn 5 ol a, four-ulxeeiml enr ixih lhe rem" Whe-els snliecn-nily flexible 2.o run over uni-vim ronds rmnoved. Fig. l is ai. seetiomd phm oi' the sinne wil-h he hodyrenxm ed. Fig. 5 is; un nlnrged horizontal seetiwn of theherehgi-:iring und ,fi-.nr box of the hack axle `suimhle for u. Il:x'ee-\\'iieelerl enr.

ln wirrying ont my invention, lhe engine .'1 is preferably placed nlmosiover the freni. axle b :md is supported from the same by means ol' the springs c, the lower halves of whirh :we bolted to hrekcts 1l on the front axle l) and -he upper halves holted to branle ets-rf on a horizontal barhfpnnsing through n. bracket l which is secured to or may he mist solid wit-h the engine casing a. The Change speed fourni-,ase li is secured at. one vnd, to the engine casing a and, at the other, tr one end of the hollmiY steel tube 'i whose other end is secured to the back axle gear case lhiwn the comer of the hollow steel tube i. runs a straight. transmission shaft l: keyed nl. une end to a spur wheel of the chauffe speed gear :xml at the other end to n1 bevel pinion Z (see Fig. 5) which genis with :L hevel livel 'm keyed te the hollow live buck axle n. "lhe transmission shaft is tapered and mrcwed at the end :xo receive the bevel pinion, wiaich,

with the bearing u. Thel body y of the can is,

preferably supported, at the front, hy the same springs r: as the engine and, nl. the buck,

l by the springs e* on the back axle.

In the case of a fom' vi heeled cur the engine is preferably supported from the front axle hy e, .lateral spring c and instead of one hellow steel imnemiasinn miie l preferably use twe, one tted within. the other. The outside tube i, is rigidly secured to ihn buck ,mile geur linx and iuoselv fitted to the change speed gear hex, While the inride tube is rigidlghammd 2o the change swcd our im);

-gine end.

and loosely fitted to the back axle gear box. This arrangement, althourrh not allowing any end play, yet allows both tubesto revolve round each other for a certain dista-nce and y n fixed. at its rear end and free at its front end thus both axles can take up different angles relatively to one another due to inequalities in the surface of theroad. The transmission shaft k runs down the center of the tubes and transmits the power to the baek axle through bevel gearing as before. The tubes are supported by the stays 'w and the engine casing y the stays All the working parts' of the transmission gear are and in fact the entire system is or may be inclosed in oil-tight eases or tubes.

When the transmission system is arrangt-d i in this manner, the rise and fall of the back wheel or wheels practically takes place round the engine as a pivot so that the movement oi the hack axle is inapprceiable at the en- As the body of the ear is not rigldly connected to the engine in any way the vibration of the latter is not felt by the oc` eupants of the car and the body can be made much lighter in structure without an expensive and separate frame. lt may, if desired, be made entirelv of wood. t

H avinfvnow fully described my invention, what I claim and t esire toseeure by Letters Patent is:-

n 1. 1n a motor ear the combination vn'th the front axie or a motor pivot-ally supportedthereon, gear for driving the back axle, a shaft directly connecting said gear with the gear of the motor, a. tube surrounding said s shaft, a second tube arranged outside of the first one, the one tube being iixed at its front end and free at its rear end while the other is in order that the Wheel axles may take up diferent angles relatively with one another and to the horizontal.

2. In a motor car the combination with the front axle, of a motor pivotally supported thereon, lateral su ports for the motor, driving gear on the bac axle, a shaft extendin from the motor and driving said gear, a tu e 'surrounding said shaft which tube is fixed at its front end and free at its rear end, and a second tube outside the first which is fixed at its rear end and free at its front end 3. ln a motor car the combination with the front axle, of a. motor pivotally supported thereon, a gear ease extending fronrthe rear of the motor, lateral supports for said gear case, a tube extending rearwnrdly from the gear ease, a shaft arranged within said tube, gearing on the back axle driven lr' said shaft, a gear case-for-'said gear, a tub cured to said case and extending'forwardly and lateral stays connected with the front. end 'of the said tube. Y'

lIntestimony whereof I affix my signature in presence of two witnesses.
